http access log extention capabilities

| Question: It is possible to add additional values to the http access
log? I want to be able to pull specific values out of the request
object, such as customer identifiers or order numbers, and put them in
the log file too. Weblogic has a way of doing this (scroll down to
'creating custom field identifiers'):
http://e-docs.bea.com/wls/docs61/ad...er.html#113868. So
I'm wondering if WebSphere has an equivalent.
From my research so far, there seems to be no easy way to add
information into the http access log using built in features. I know
that IBM HTTP Server is only a light-weight wrapper around Apache.
Therefore, I first searched the Apache documentation that describes the
available configurable features pertaining to logging, in particular the
access log files:
http://httpd.apache.org/docs-2.0/logs.html#accesslog
IBM has republished this documentation, adding their minor extensions,
in an official publication that can be found at:
http://www.redbooks.ibm.com/abstrac...5132.html?Open. Again, these
encompass options relating only to the configurability of the logging
format.
Short of writing a web server plug-in which mimics the functionality
provided by Weblogic, there seems to be no WebSphere equivalent to
Weblogic’s custom field identifiers, which leverage ELF (extending
logging format). WebSphere does provide an option to use ELF as the
format for logging, but no documentation was found which claims
extensibility in that realm.
Any and all help is greatly appreciated.

You want to pull the info from the Query string (like
http://host/myservlet?custid=123&ordernb=456) and have it in the access.log
file ?
If so, I don't think Apache / IBM HTTP Server has this feature. You can log
the Query string
(http://httpd.apache.org/docs-2.0/mo...ig.html#formats), but not
split it (AFAIK).
Alternatively, you could have a servlet filter log this information in a
file of its own with all other info, mimicking the web server log file
layout.

string. It's in the request scope, but not the url for the page.

Then Apache will never see it. You'll have to do your logging from
within your app for that.
